Planning your retail media budget for 2027 should start long before January.
For CPG brands, retail media is increasingly connected to the broader retail growth plan: where your products are distributed, which retailers you want to grow, what new SKUs you are launching and how much sales each retailer needs to generate.
The biggest mistake is treating retail media as one annual number.
A better approach is to build your 2027 budget retailer by retailer and SKU by SKU, using actual campaign performance to determine where additional spend can generate incremental sales.
Here is how to do it.
1. Start With Your 2027 Distribution Plan
Your retail media budget should follow your retail distribution.
Before deciding how much to spend, map where your products will actually be available in 2027.
Include:
- Current retailers and marketplaces
- Planned retailer launches
- New geographic distribution
- New SKUs and product launches
- Marketplace expansion
- Retailer-specific sales targets
For example, a brand selling through Whole Foods, Walmart and Instacart should not simply divide its advertising budget equally between all three.
The opportunity will depend on factors such as distribution, product availability, search demand, competition and current sales at each retailer.
Retail media planning should therefore start with the commercial plan, not the media plan.
The retailer gets your product onto the shelf. Your next challenge is generating enough demand and sell-through to keep it there.
2. Build the Budget Retailer by Retailer
Once you understand your distribution, create at first a separate retail media budget for every retail media network.
For example:
| Retailer / Network | 2027 Priority | Current Performance | Planned Action |
|---|
| Walmart | High | Existing campaigns | Scale |
| Instacart | High | Strong ROAS | Increase investment |
| Target | Medium | New launch | Test and optimize |
| Amazon | High | Mature account | Protect + grow |
| New retailer | Test | No data yet | Launch test |
This matters because the economics of each network can be very different.
A campaign that performs exceptionally well on Instacart does not automatically justify the same level of investment on Walmart or Target.
Allocate budget according to retailer-level opportunity and performance, rather than using one universal percentage across every network.
3. Plan at SKU Level — Not Just Brand Level
Retail media performance can vary significantly between products from the same brand.
One SKU might:
- Have stronger search demand
- Convert better
- Carry better margins
- Have better retailer distribution
- Face less competition
- Generate a much stronger ROAS
Another SKU may struggle to convert even with significant advertising support.
That is why your 2027 retail media plan should ideally include budgets and performance targets at the SKU level.
This makes it easier to shift investment toward the combinations of retailer + product producing the strongest returns.
4. Use 2026 to Test Before You Set the 2027 Budget
If you do not have enough historical retail media data, your 2027 budget will largely be a guess.
Use the remaining months of 2026 to create the benchmarks you need.
Run campaigns now to understand:
- Conversion rate
- ROAS
- Sales generated
- Spend capacity
- Search volume
- Performance by SKU
- Performance by retailer
- Branded vs. category keyword performance
Do not expect a new campaign to immediately tell you its full potential.
Allow time for campaign setup, product feeds, data collection and optimization. For a new retailer or network, planning for approximately two months of testing and ramp-up can give you a much more useful baseline for the following year’s budget.
The objective is not simply to spend your test budget.
It is to answer:
If we put another dollar into this retailer and SKU, what are we likely to get back?
5. Make Sure Your Product Pages Can Convert Before Scaling
Advertising cannot compensate indefinitely for weak product listings.
Before substantially increasing your retail media investment, check whether shoppers arriving at your PDPs have enough information to make a purchase.
Review:
- Product and category naming
- Product images
- Key benefits and USPs
- Certifications
- Functional benefits
- Ratings and reviews
- Product descriptions
- Product feeds
- Pricing and promotions
- Availability
Testing retail media is one of the ways to identify conversion problems.
But once the data shows that low conversion is limiting performance, fix the underlying problem before aggressively scaling spend.
6. Establish a Meaningful Testing Budget
Very small budgets can make retail media difficult to evaluate.
If a campaign generates only a handful of clicks, you may not have enough data to understand which keywords, products or bids actually work.
As a practical starting point for challenger CPG brands, you need to plan approximately $50–$100 per day per priority retailer or network during an active test.
That is roughly:
- $1,500/month at $50/day
- $3,000/month at $100/day
This is not a universal minimum, it can be higher. The right number will depend on CPCs, category competition, product assortment and the number of campaigns you are testing.
The principle is more important than the exact number:
Give each test enough budget to produce actionable data.
7. Set Different ROAS Expectations for Testing and Optimized Campaigns
Do not build your entire 2027 budget assuming every dollar will immediately deliver your target mature ROAS.
New campaigns need time to learn.
During early testing, performance may be materially lower than after keywords, bids, budgets and SKU-level structures have been optimized.
For planning purposes, create at least two scenarios:
Testing scenario: conservative expected ROAS while campaigns gather data.
Optimized scenario: expected ROAS once inefficient spend has been removed and investment is concentrated on the strongest products, keywords and retailers.
For example, a brand might model:
- Initial / automated campaigns: around 2x ROAS
- Optimized campaigns: 4–5x+ ROAS
These should be treated as planning assumptions rather than universal industry benchmarks. Your own historical performance should always take precedence once sufficient data exists.
8. Calculate Retail Media Budget From the Sales Opportunity
Once you have a realistic ROAS target, you can reverse-engineer your required media investment.
A simple formula is:
Retail Media Budget = Target Ad-Attributed Revenue ÷ Target ROAS
For example:
If you want retail media to generate $500,000 in ad-attributed sales and you believe an optimized 5x ROAS is achievable:
$500,000 ÷ 5 = $100,000 retail media budget
You can then break that budget down by retailer and SKU based on their expected contribution.
Do not stop there, however.
The important question is whether each campaign can actually absorb the planned budget without efficiency deteriorating.
A theoretical $100,000 budget is irrelevant if your campaigns can efficiently spend only $60,000.
9. Identify Your Campaigns’ Spend Capacity
One of the most overlooked parts of retail media budgeting is spend capacity.
A campaign may be producing excellent ROAS precisely because it is currently capturing only the most efficient demand.
If you double the budget, ROAS may remain strong — or it may decline.
That is why 2027 planning should consider both:
Efficiency: How much revenue are we generating per advertising dollar?
and
Scale: How much money can we deploy while maintaining acceptable efficiency?
Your strongest opportunities are campaigns where both are high.
If a campaign consistently performs well and runs out of budget, increasing investment may unlock additional sales. Retail platforms themselves increasingly provide budget and lost-opportunity signals to help advertisers identify campaigns constrained by budget.
10. Leave Part of Your Retail Media Budget Available for New Opportunities
Do not allocate 100% of your 2027 retail media budget in advance.
Your distribution will change.
New SKUs will launch.
Retailers may expand your listings.
Some campaigns will outperform expectations, while others will fail to scale.
Keep part of your budget flexible so you can move investment toward what actually works.
For example, your annual plan might include:
- Core investment: proven retailers and SKUs
- Growth investment: campaigns with demonstrated potential to scale
- Testing investment: new retailers, products and strategies
- Flexible reserve: retail media budget available for opportunities identified during the year
The exact percentages should depend on how mature your retail media program is.
11. Reallocate Retail Media Budget Continuously
Your January allocation should not still be your allocation in June simply because it appeared in the annual plan.
Retail media produces relatively fast feedback.
Use that information.
Review performance across:
Retailers → Campaigns → SKUs → Keywords
Then shift retail media budget toward the areas generating the strongest incremental sales at an acceptable return.
For example, if one SKU is delivering significantly better returns on Instacart than on another network, additional budget may produce more value there.
The goal is to maximize the business impact of the total retail media investment.
A Simple 2027 Retail Media Budget Framework
When building your plan, answer these questions for every retailer:
- Where will we be distributed in 2027?
- Which SKUs do we need to grow?
- What sales do we need to generate?
- What did campaigns achieve in 2026?
- What ROAS can we realistically expect?
- How much can campaigns efficiently spend?
- Which retailers and SKUs should receive incremental budget?
This gives finance and commercial teams something far more useful than a single fixed media number.
How Much Should You Budget for Retail Media in 2027?
There is no single percentage that works for every CPG brand.
Your ideal retail media budget depends on:
- Distribution
- Retailer sales targets
- Number of SKUs
- Category competitiveness
- CPC
- Conversion rate
- ROAS
- Product margins
- Campaign maturity
- Available search demand
- Expansion plans
The strongest 2027 budgets will therefore be based on actual 2026 performance data rather than generic industry averages.
If you are already running retail media, use your existing campaigns to determine where additional spend can drive profitable incremental sales.
If you are just starting, use 2026 to test your priority retailers, establish performance benchmarks and determine realistic spend capacity before committing to your full 2027 plan.
